HANDLE FOR CROSSCUT-SAWS.

Speccation of Letters Patent.

Patented Nov. 7, 1905.

Application filed February 12, 1903. Renewed April 22, 1905. Serial No.256,994.

T0 aM. whom, t may concern: I

Be it known that I, WILLIAM KRoNENwET- TER, a citizen of the UnitedStates, residing at St. Marys, in the county of Elk and State ofPennsylvania, have invented a new and useful I-Iandle for Crosscut-Saws,of which the following is a speciiication.

The invention relates to improvements in handles for crosscut-saws.

The object of the present invention is to improve the construction ofhandles for crosscut-saws, more especially the means for securing thesaw-blade to the handle, and to provide a simple, inexpensive, andeflicient de vice of great strength and durability adapted to be readilyapplied to an ordinary crosscutsaw and capable of securely gripping thesame and of eifectually preventing the handle from becoming loose.

With these and other objects in view the invention consists in the novelconstruction and arrangement of parts hereinafter fully described,illustrated in the accompanying drawings, and particularly pointed outin the claim hereto appended, it being understood that changes in theform, proportion, and mie nor details of construction within the scopeof the claim may be made without departing from the spirit orsacrificing any 'of the advantages of the invention.

In the drawings, Figure 1 is a side elevation, partly in section, of ahandle provided with a device constructed in accordance with thisinvention. Fig. 2 is a transverse sectional view of the same. Fig. 3 isa detail perspective view of the cap.

Like numerals of reference designate corresponding parts in all theiigures of the drawlngs.

1 designates a cylindrical cap designed to be constructed of suitablematerial, such as malleable metal, and adapted to receive the lower endof a crosscut-saw handle 2, as clearly illustrated in Fig. l of thedrawings. The cap, which is open at its inner or upper end, is providedat its lower end with a projecting rim or bead, and it is connectedthereat by an inwardly-extending horizontal ilange or portion 3 with atube 4, formed integral with the said iange 3 and extending inward asuitable distance, preferably beyond the center of the cap, as shown;but it may be of any desired length. The cylindrical portion of the cap,which forms a ferrule, extends beyond the shorter inner tube to embracea solid portion of the handle, whereby the dep firmly wedged in place,being driven into the cap in any suitable manner.

The cap is provided on its interior with longitudinal ribs 6, which areembedded in the wood of the handle, whereby the cap is iirmly held onthe handle and is effectually prevented from slipping when the handle isrotated for clamping a saw-blade. The tube is provided at its upperportion with interior screw-threads 7 to engage a threaded portion 8 ofa rod 9, which is provided with a loop 10 of the ordinary constructionand which receives in its opening or loop one end of the blade of acrosscut saw. The handle is adapted to be rotated on the rod which formsa spindle for the same, and the smooth lower face at the end of the capis adapted to firmly engage the upper edge of a saw-blade, whereby thelatter is securely gripped and fastened to the handle. The handle isadapted to be tightened by rotating it on the threaded rod or screw, sothat there is no liability of the handle becoming loose through use. Thehandle may be readily unscrewed to detach it from a saw-blade, and itcan be quickly transferred from one blade to another. The device may bereadily applied to a saw-handle by simply driving the same into the cap.The handle, which is constructed of wood or any other suitable material,is not weakened by the adjustable connection between the cap and therod, which when the parts are assembled is rigid with the said cap. Asolid portion of the handle extends into the cap, so that there is noliability of the handle breaking off at the inner end of the cap whenthe saw is in use.

The interior screw-threads of the tube are located at the upper portionthereof, and the lower portion 1 l of the same is smooth to receive andsupport the upper smooth portion of the rod. The upper end of the tubeis open, and the screw or threaded portionv of the rod may extendthrough it into the bore of the handle.

What I claim is- The combination with a saw-handle, of a IOO saw-bladeand provided with a threaded inner portion engaging the screw-threads ofthe tube, substantiazly as described.

In testimony that I claim the foregoing as 15 my own I have hereto aXedmy signature in the presence of two witnesses.

WILLIAM KRONENWETTER.
